Installation & Configuration

If you want to increase data storage on your Nutanix cluster, but do not want any AHV VMs to run on that node, you can add a Never-Schedulable Node to your cluster. AOS will not run any VMs on a never-schedulable node, whether at the time of deployment of new VMs, during the migration of VMs from one host to another (in the event of a host failure), or during any other VM operations. Therefore, a never-schedulable node configuration ensures that no additional compute resources such as CPUs are consumed from the Nutanix cluster.With the release of Foundation 4.1 and higher, any G6 or G7 node can now be used as a storage-only node. You can add any number of never-schedulable nodes to your cluster!To learn more about the requirements and the procedure to add this node, click here. Also, check out KB-6819 for further instructions.

I have a lot of virtual machines running with latest Debian 10 distribution (version 10.2 and next 10.5).When will be available Nutanix Guest Tools for this distribution? It’s a mess to receive warnings everyday with the message of NGT not installed in these machines.

There could be many reasons why an administrator would want to perform a factory reset of the IPMI/BMC module. Whatever the reason maybe, knowing the different options and its differences is important.Using ipmitool, we can perform 3 types of resets each with its own implication. Reset BMC  Partial factory reset (IPMI and BMC reset but will preserve Network settings) Full factory Default reset (Potential to lose IPMI network settings)Before you execute any of these commands, note the IP_Addr, Net mask and GW IP_Addr for the IPMI. ipmitool lan printUsage note: On VMware ESXi hypervisor, place a leading "/" in front of "ipmitool", for example, "/ipmitool". The executable is located at the top-level root directory.Check out the KB-8123 for detailed instructions.

 Can't I remove the interface included in the bond with ovs-vsctl For example If br0 contains interfaces eth0 to 3 in bond name br0-up, I want to clear eth0, eth1. If I can't, is there a command to update or remove interfaces like manage_ovs --bridge_name br0 --bond_name br0-up --interfaces eth2,eth4 update_uplinks command in ahv? Thank you for always helping me

There are cases where we forget the password for "nutanix" user which is used to login to Move Web GUI console. Nutanix user is a Move app user and not a user on the Move-vm. Therefore, "passwd nutanix" does not work and to reset it we need to follow the manual process mentioned in the below KB article: How to reset nutanix user password in move for Web GUI accessThe procedure mentioned in the above article is to reset the password for "nutanix" user only and not admin (cli) user.  Password reset of "admin" who is a user on the move-vm would not be possible as it is the only user exposed on the move-vm. Allowing to reset the "admin" password externally would cause security violations in case of malicious actions. The only way in this case would be to re-deploy the Move appliance. The following documentation includes the step by step process of deploying a new Move VM: Move Deployment

We have to do a deployment of 5 HPE DX nodes with AHV as hypervisor. Is it mandatory to have the iLO ip address in the same subnet as CVM & Host ? If not then do we have to give 2 IP addresses to foundation VM ? Let me know if anything else is needed.

I'm looking for some advice.My company recently purchased a used 3460-G4. We're a professional services firm and we want to have it for our lab so we can stand up stuff like ERA, CALM, etc. and bang around on it. You know, lab stuff!We have been trying to Foundation (4.5.4.1 & 4.5.3.1) the block but I am running into a problem with Foundation failing when trying to mount the Phoenix image on the nodes. Here's how things currently stand:BIOS has been upgraded to latest recommended version on Nutanix Support site. (G4G5T6.0)BMC firmware has been upgraded to latest recommended version on Nutanix Support site. (3.64)Each node has x2 SSDs, which this system appears to recognize (I ran an ESXi installer on one of the nodes to test. The installers saw the drives)Each node has 64GB of RAM. The RAM is confirmed to be compatible according to SuperMicro's site.The Motherboard is the X10DRT-P from SuperMicro.IPMI has been set on each node and I can log into the IPMI mgmt page.At first I was wo

In our environment, eth2,3,4,5 is assigned to br0. The bonding policy uses active-backup and the current active interface is eth2.I want to leave only eth2,3 in br0 with the following command while the cluster is online.allssh manage_ovs --bridge_name br0 --bond_name br0-up --interfaces eth2,eth3 update_uplinks1. Is it possible to proceed without stopping the cluster?2. What if I need to stop the cluster?

Hello NX, I have a question, is it okay if i will disable the SSL port of my Nutanix CVM's and management port? Because if shows vulnaribility into the scan. What would be the effect if i will disable those ports.. Thank you.

Dear Team,My cluster is out of storage now,I have one Lenevo SAN Storage(V3700).can you please suggest how to utilize this storage with Nutanix AHV cluster. 

This is the scenario I have:We have a four node cluster running Hyper-V. We want to migrate/reload/replace with AHV. There is nothing on this cluster that needs to be preserved.I tried the Foundation Portable application, but it does not seem to discover the nodes. I suspect that is because they are neither bare-metal nor factory imaged at this point. (based on this article - https://portal.nutanix.com/page/documents/details?targetId=Field-Installation-Guide-v4_5:Field-Installation-Guide-v4_5)This is a “retail” cluster, so I do have support. I just don’t know if it’s appropriate to tie up a support engineer for the time it would take to reload a cluster. So I was hoping to at least get started on my own. I did some googling and searching here and the KB. But I suspect my search terms are either too broad or maybe even far too specific. All I get back is how to setup a brand new cluster. 

Recently, we upgraded AOS and AHV in a 6-NX-1065-G5 nodes cluster. Those nodes have only 1 Gbps interfaces and the upgrade process got stuck many times while actively moving guest VMS to other nodes when setting each node to maintenance mode. Tech support told us this happened because new AOS and AHV versions were designed to work at 10 Gbps, which we know is a best practice, but a hardware upgrade would be needed in our scenario then.Question: I´m guessing configuring the four uplink interfaces as Balance-SLB bond may help, having a total bandwidth of 4 Gbps in optimal conditions, Has anybody gone through this problem and applied this cure? Was it useful or… Not enough? Thanks in advance

Hello,May I please ask for some help with understanding vStore mapping in Data Protection?Setup: two identical HCI clusters, both run production workloads. A Protection Domain with Async DR is being configured to replicate a subset of VMs from one cluster to another for DR purposes, as well as for migration scenarios. Hypervisor: ESXi.Question: Can vStore mapping be done to a container with live running VMs?In more general view, I consider a scenario where each of the two clusters not only runs its portion of production workloads, but also is the replication target for the other cluster. Should the replication be mandatorily mapped to a separate/dedicated container, or can it go to the same container as the local VMs run from? I.e. how about having a single container for all UVM-s in each cluster, and vStore mapping in each cluster for these two containers?Thank you.

Hello All, How should I provide SMTP Server settings when the mail server is in the cloud (Office365) ?As shown below, I tried with this mail server smtp.office365.com but the “email test” failed : Thanks in advance.

Are you someone with the following condition? Your Nutanix Cluster has grown so much that it needs to be moved to a different (bigger) network segment (VLAN).  You are daunted by the amount of changes that moving a cluster to a different network space could result in. Have no fear!The procedures are documented as per the CLUSTER IP ADDRESS CONFIGURATION section of the ACROPOLIS ADVANCED ADMINISTRATION GUIDE. From a high level, the procedures involve some preliminary verifications along with securing some downtime for the cluster (as the changes need to be made while the cluster is in a “stopped” state). From there, it is simply a matter of changing the IPMI and hypervisor IP addresses followed by the execution of a script called “external_ip_reconfig” which handles the procedures for changing the IP addresses of the CVMs. Follow that up with some post verifications and your existing cluster should be successfully running on a new network segment!

Hello,i have three nodes configured with nutanix AHV and in the storage container i am seeing 3 containers but one of the containers is not working i can’t even update the setting for it please it has over 21 tb space and i couldn’t use it so what do i have to do to make it available. 

Hi guys, a non technical question about a customization option that I can’t find anywhere. I have two Prism Central used for Synchronous replication. To Identify them at first sight I have customized title and colors of the login page. It was a bit disappointing to not find the customized name on the browser tab or at least on the menu bar title. Even after editing the cluster params to give a name to the PC cluster (only one VM as for now) the name stick on “Prism Central” on the tab and “Prism” on the menu bar.Considering I’m working on a Synchronous replication and that all the objects involved have the same name (Protection Policies, Recovery plans, categories), sometimes i found myself working on the wrong Prism Central. It would be easier to have the PC name always visibile. Any idea? Thanks in advanceil_gianK’ Tab and menu bar title 

Upgraded PC to 2020.7 and ncc to 3.10.1.  Now getting the warning:Possible CauseThe current feature capabilities of Prism Central require resource on the Prism Central VM to be increased for optimum performance. RecommendationIncrease the resource of the Prism Central VM. Please refer KB-8932 for guidance. I am at 6 vCPU and 32 GB RAM for PC VM.  Not getting too far with support.  I was wondering if others have seen this issue.The KB article mentions “large” and “small”.  I don’t remember setting PC size.  How does it know if it is large or small?  Mine thinks it is large, but I only have around 200 VMs in 3 Clusters.  Only using a single PC, not scaled.

When performing maintenance on a CVM, it is important to not treat it as a regular guest VM. This is because there are crucial services running on each CVM which need to gracefully respond when a CVM goes offline.If you need to shutdown a CVM and are running ESXi, you might otherwise think to simply go to vCenter, right-click on the CVM, and select the “Shut Down Guest OS” option. However, that procedure will not properly shut down the CVM and allow the services to gracefully respond.Instead, in using the cvm_shutdown script, it will first place a necessary HA route in the hypervisor, to redirect storage requests to another CVM, before shutting down the CVM. This will also allow the services to gracefully respond to the CVM being offline.More information and options regarding this script can be found in KB 3270
